Cold and accumulating snow
While Tropical Storm “Epsilon” meanders over the central Atlantic, colder-than-normal air has dominated the weather scene in recent days from the interior Northwest to the Northern Plains. In fact, this type of colder-than-normal weather pattern is likely to hold for much of the time during the next week to ten days and it will actually spread eastward to across the Great Lakes and portions of the Northeast US. It looks like the colder-than-normal air will have trouble making it all the way into the Mid-Atlantic region until sometime next week.
In addition to the cold, accumulating snow has already taken place in places like Montana and significant accumulating snow is likely to extend eastward during the next few days across the Dakotas, Minnesota and Wisconsin. In terms of specific snowfall reports, yesterday actually turned out to be the snowiest October day on record in Great Falls, Montana with 8.4 inches that bested the prior record of 6.6 inches set on October 13, 1975. The two-day total of 13.3 inches in Great Falls is its snowiest October two-day record since October 3rd and 4th, 1957 when 8.4 inches piled up. Some areas across the Dakotas, Minnesota and northern Wisconsin can receive as much as 6-12 inches of snow during the next few days as low pressure pushes out of the interior Northwest and towards the Great Lakes.
